From the upper end of the journal 39 projects a trunnion 43, the outer end of which is lefthand threaded at 44 to receive a cap nut 45. The trunnion 43, which is square in cross section, passes freely through the circular end portion of a radial slot 45 in the head I3 as shown in Figure 5. Said circular end portion of the slot 46 is bounded by a collar 41 freely receivable in a circular recess 48 formed in the central portion of a disk '49 having a square opening 58 centrally thereof through which the square trunnion 43 extends to provide an operative connection between the disk and trunnion. The disk 48 is yieldingly urged axially into engagement with the head I3 by a short coil spring 5I, and the disk and spring are enclosed by a cupshaped cap 52 having a central opening freely receiving the trunnion 43, and being confined thereon by the nut 45.

The disk 49 is provided with a circular series of openings 53 with any of which pins 54 on the head I3 are adapted to co-act in providing an operative connection between the hinge member I8 and the disk, As shown in Figure 8, each pin 54 is beveled in a direction circumferentially of the head I3 to provide a cam surface 55, and as shown in Figures 1, 4 and 5, the disk 48 is provided with a depending lug 56 projecting through a slot 51 in the cap 52 and adapted to co-act with lugs 58 and 58 on the head I3 to limit circumferential adjustment of the disk on the head, all for a purpose to be fully described hereinafter.

It is to be noted that with the hinge members I and II secured, respectively, to the door D and jamb J, the door can be hung and unhung when the lower nut 31 and the upper assembly consisting of the nut 45, cap 52, spring I and disk 49, are removed, as the hinge member I8 can be separated laterally from the hinge member II by the provision of the radial slots 34 and 46 in the heads I4 and I3, respectively, which permit the trunnions 43 and 32 to be disengaged from the heads. However, it will be clear that when the nut 31 and the aforestated upper assembly are applied as shown in Figure 1, they co-act with the heads to maintain the hinge members connected in hinging relationship.

The actuating bar 48 co-acts with a nut N in the form of a partially flattened and spirally twisted portion 60 of a tube 6I- enlarged at one end to provide a piston 62 working in the cylinder defined by the casing I8. The nut and piston unit are confined against rotation and to movement axially in the casing by a stud 63 of rectangular cross section fixed by a pin 54 to the lower plug 23 and having a slidable keyed co-action with a rectangular opening 65 inthe piston portion of the nut N.

A relatively heavy coil spring 66 is mounted in the casing I8 to surround the actuating member A and the nut N, the upper end of the spring having a hooked connection at 61 with the projecting extremity of the pin 42, whereas the lower end of the spring has an identical hooked connection at B8 with a pin 59 projecting from the nut N.

As the actuating member A is rotated relative to the casing I8 upon each hinging movement of the member I8 relative to the member II as will eiectopening of the door D, the actuating member will co-act with the non-rotatable nut N to feed the latter axially from the position shown in Figure l towards that shown in Figure 2 so as to compress the spring 66 between the collar 4I and the piston 62. Due to the hooked connection of the spring BE to the actuating member A through the medium of the pin 42, and to the nut N through the medium of the pin 69, the spring will be wound and loaded torsionally as well as compressionally or axially during opening movement of the door.

The interior of the casing provides a fluid chamber C, and all unoccupied space therein is intended to be lled with a suitable liquid such as castor or other oil which acts as a checking medium to retard the closing movement of the door during which the liquid is forced to bypass from the upper to the lower side of the piston 52 through the annular space provided by a pre-calculated clearance between the piston and the internal wall of the casing I8.

The piston 62 is provided with ducts 10-10 extending from one side of the piston to the other and controlled by a valve 1I in the form of a spring metal plate secured in any suitable manner, such as by soldering, at one point 12 in its periphery to the piston. The plate freely works in a recess 13 in the piston and is bifurcated to freely straddle the stud 63 and cover the ends of the ducts during closing movement of the door, yet to fulcrum about the point of attachment 12 during opening movement of the door in response to pressure of liquid in the ducts, whereby to permit the by-passing of liquid through the piston in a relatively large volume, as indicated by the arrows in Figure 2, so that the opening movement of the door will be unrestricted. In order to permit free passage of liquid into and out of the tube 6I, an opening 14 is provided therein.

The operation of the invention is as follows:

With the door closed, the parts of the device will occupy the position shown in Figure l. Upon opening the door, a corresponding angular movement will be imparted to the actuating member A from the hinge member I8 through the medium of the intervening operative connection provided by the disk 49, thus causing the actuating member to co-act with the non-rotatable nut N in axially feeding the latter towards the position shown in Figure 2, `during which movement the liquid in the chamber C is free to bypass through the ducts 18-18 of the piston 62. Thus the opening movement of the door` will be unrestricted by the liquid and will serve to load the spring 86 oompressionally and torsionally.

Upon releasing the door the spring 55 will urge the door closed, but the closing movement will be effectively retarde-d by the liquid, which can now only by-pass around the piston.

In order to compensate for doors of different weights which require different loadings of the spring 56 to restore the door to closed position, the disk 48 can be circumferentially adjusted, preferably when the door is closed, so as to vary the initial loading of the spring.

For example, should the spring loading be insufficient to close the door, a turning movement exerted with a wrench upon the nut 45 in a direction to tighten the latter (counter-clockwise in Figure 1) will correspondingly rotate the actuating member A to increase the torsional and compressional loading of the spring 56. It will be apparent that the disk 49 will be correspondingly rotated due to the fact that it rides over .m

the cam surfaces 55 of the pins 54 which enter successive openings 43 of the disk as the disk is advanced rotationally, the spring 5I yieldingly retaining the disk in the selected position of circumferential adjustment, so as to maintain the desire-d initial loading of the spring 66. Thus the disk 49 and its associated parts broadly constitute a means by which the loading of the return spring 66 can be varied to compensate for doors of different weights in order to insure operation of the device with maximum efliciency.

Mounted on the inner tube I8a of the casing I8 between the outer tube sections I 8b and I 8c so as to normally rest by gravity on the annular1 shoulder formed by the upper end of the tube section IBc is a sleeve I5 which constitutes a holding means and passes freely through an opening I6 in the portion I 9 of the member I I.

'I'his sleeve is provided on its upper edge with a circular series of notches TI and with a radial lug 'I8 which projects into a slot 'I9 in the portion I 2 of the member I 0 so that the sleeve is confined against rotation relative to this member yet is capable of vertical adjustment on the tube I 8a of the casing I8.

Mounted on the tube I8a above the sleeve 'I5 so as to be concealed by the skirt I8d is a torsional spring 80 which is normally constricted upon the tube I8a and terminates at one end in a laterally bent extremity constituting a lug BI adapted to enter any one of the notches ll' upon manually raising the sleeve l5.

When it is desired to retain the door in an open position, the sleeve 'I5 is raised to engage the lug 8| with one of the notches '11, so that by temporarily holding the sleeve raised until the door is release-d, the action of the spring 66 in tending to close the door, will force the lug tightly against one wall of the co-acting notch. As the force with which the spring 80 is constricted upon the tube I8a is suicient to prevent its rotation on the tube under the urging action of the return spring 66, the sleeve will be maintained in its raised position to hold the door in the selected open position.

However, should an attempt be made to force the door closed when thus held open, the constricting force of the spring Btl upon the tube IBa will be overcome, thus permitting the spring 80 to be rotated on the tube by the sleeve 'I5 and the door to be closed without damage to the device and/or to the door. It will thus be appreciated that the sleeve 15, spring 89 and the associated parts broadly constitute means by which the door can be releasably maintained in various open positions, yet yielding to an excessive force applied to the door by permitting the latter to be moved in order to prevent damage to -the door and the device.
